SPINNING MACHINE.

' r Application filed September 27, 1923. Serial No. 685,131.

To all whom it may concern:

Be it known that I, ROBERT E. NAUMBURG, a citizen ofthe United States, residing at Winchester, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Spinning Machines, of which the following is a specification.

This invention relates to roving, spinning and twisting machines, and is especially concerned with such machines, whether of the cap, ring, or fiyer type, which are equipped with a reverse roll located in front of the drawing or feed rolls. For convenience these machines will be hereinafter referred to as spinning machines, and the thread, roving or yarn handled by them will be hereinafter referred to as thread.

In prior machines of this character provision has been made'for the dofling and donning of the bobbins and other thread packages either by allowing the proper distance vertically between the upper ends of the spindles and' the reverse" roll for these operations, or else by driving or mounting the reverse roll in such a manner that it can be moved out of the way for removal of a bobbin from the spindle or the placing of an empty bobbin thereon. The first of these arrangements is objectionable for the reason that the length of the package that can be built in a given machine is very definitely limited, and for the further reason that in building a long thread package the length of the balloon made by the thread as it is spun or twisted becomes excessive. This necessitates the use of a lighter traveller if the same spindle speed is to be maintained, and the light weight traveller is very liable to burn up or melt. The arrangements which have been provided for mounting the reverse roll so that it can be moved out of the way of the thread package are also objectionable, either because they introduce lost motion into "the driving of the reverse roll, which results in breaking the thread or ends in starting up the machine, or else because of the complications introduced in the driving and supporting mechanism for the reverse roll.

It is the chief object of the present invention to devise a machine which will not "be subject to these limitations. The. in-

vention provides a construction which facilltates the dotting operation and makes it possible to build longer thread packages than otherwise could be made.

The nature of the invention will be readily understood from the following descript'ion' when read in connection with the accompanying drawings, and the novel features will be particularly pointed out in the appended claims.

In the drawings, I

Figure 1 is a front elevation of a small part of a spinning frame at one end thereof and illustrates one embodiment of the invention;

Fig. 2 is a vertical, transverse, crosssectional view through the front part of the spinning frame shown in Fig. 1; and

Fig. 3 is a view similar to Fig. 2 but showing the parts in dofling position.

The drawings show the invention applied to a ring spinning frame, although it could also be used to advantage in the other types of spinning, roving or twisting frames, as will be evident to those skilled in this art. The machine shown comprises a spindle rail 2 supporting a series of spindles 3. Partially filled bobbins 4 are shown in Figs. 1 and 2 supported on the spindles 3. The strands of material to be spun are fed between drawing rolls 5 mounted in the usual frame 6 and are led over a reverse roll 7 to the usual traveller which'runs on a ring 8 carried by a traversing ring rail 9. This ring rail is supported on the upper ends of a plurality of vertical rods 10 which extend through holes formed in the upper and lower horizontal flanges of the spindle rail 2, and they rest at their lower ends on the usual cross shaft levers 12. These levers are operated by the builder mechanism with which spinning frames customarily are equipped, it being understood that these mechanisms operate through the rods 10 to move the ring rails 9 up and down, giving them the necessary traversev to effect the winding or building of the-thread in the desired manner on the bobbins 4.

The mechanism so far described is substantially like spinning frames of known construction except that the vertical distance between the reverse rolls 7 and the tops of the spindles 3 is much shorter than in the common commercial machines.

In the illustrated embodiment of ,the

present invention, the spindle rail 2 is provided at its opposite ends with ears 14.- which receive pivot pins supported in the end frame pieces 16 of the machine, so that the rail 2 can swing or tip about horizontal axis. A shaft 17, which runs the entire length of the machine, has a series of arms 18 extending downwardly therefrom and connected by links 19 to ears 20 which are secured to the lower edge of the rail2. Secured to the rock shaft 17' is a toothed sector 21 meshing with a worm 22 mounted fast on a shaft 23 which is supported in a bracket 241: bolted to the frame piece 16. A hand wheel 25 is keyed to the forward end of this shaft. 7

In using this machine the usual spinning practice is followed, and when the bobbins are filled, the machine is stopped and the ring rail is wound down in the usual manner. The spindles are then tipped forward, as shown in Fig. 3, simply by rotating the hand wheel 25. Such rotation results in rocking the shaft 17 in a counter-clockwise direction, Figs. 2 and 3, and this motion is transmitted through the links 19 to the spindle rail 2, thus tipping this rail about the pivots 15. -This mechanism also serves to hold the rail in its tipped position until the dotting operation has been completed.

1. It will be evident that the ring rail 9 moves in unison with the rail 2 due to the fact that the rods 10 are compelled to swing with V the rail 2.

In order to support the rods 10, and consequently the ring rail 9, during the dofiing operation, each of the levers 12 is provided with a curved xtensionor segment 27, and the lower ends of the rods are provided with rolls 28 to run on these curved members. The rods thus are maintained at all times in their cooperative relationship to the mechanism that operates them.

When th dofling operation has been completed, the hand wheel 25 is rotated in a reverse direction to swing the spindles back into their operative positions again.

It will now be evident that this arrangement permits the building of long bobbins without providing an excessive distance between the upper ends of the spindles and the reverse roll or drawing rolls. It thus avoids the excessive ballooning which otherwise proves troublesome in making long thread packages. Furthermore, this arrangement avoids any complication of the driving mechanism for the reverse roll or the supporting means therefor, this'roll being maintained at all times in a fixed position.

While I have herein shown and described the best embodiment of my invention that I have so far devised, it will be appreciated that this embodiment may be modified in various particulars without departing from the spirit or'scope of the lnventlon. For

example, the reverse roll 7 need not nece sarily be of circular cross sectional outline, but may be fluted or of polygonal form in cross section. 1

Having thus described my invention, what I desire to claim as new is:

1. In a spinning machine, the combination of a ring rail, a spindle rail, a plurality of spindles supported in said spindle rail, drawing rolls mounted in cooperative relationship to said spindles, a reverse roll for engaging the strands of material to be spun between said drawing rolls and said spindles, means for imparting a vertical traverse movement to said ring rail, and mechanism for tipping said rails in unison to move said spindle into dofling position, said ring rail being maintained in cooperative relationship to said means in both its tipped and normal positions.

2. In a spinning machine, the combination of a ring rail, a spindle rail, a plurality of spindles supported in said spindle rail, a plurality of vertical rods supporting said ring rail at their upper ends and guided in said spindle rail for vertical movement, mechanism for tipping said rails in unison to move said spindles into doiiing position,

and means for engaging the lower ends of said rods to impart a traverse movement to said ring rail, said means including a lever having an extension curved to sup ort the lower ends of said rods when tey are tipped.

a plurality of rings supported in said rail in cooperative relationship to said respective spindles, and means, for tipping both said spindle rail and said ring rail to facilitate the dofling operation.
